Sputtering issue..
Today i replaced my spark plugs aswell as installed new K&N filters and removed my carbon filters.. now my car will randomly sputter like its misfiring or something when accelerating. this has only happens at freeway speeds, when on city streets the car performs fine. I installed all the plugs correctly with a 0.040 Gap which is what the plugs i removed were set to. Does the ECU need to adjust at all to the better air flow? it seems to be occurring less with the more i drive, if this was an issue with the spark plugs or a coil it would be a constant issue, correct? also wouldn't it throw a CEL if it was an issue with the plugs i installed?

Does anyone know if this is more related to the new filters and removal of carbon filters? Again I feel like if this was an issue with my spark plugs it would be consistent.. I know with BMW the ECUs are adaptive, are MBs the same? Like I said before the more I drive the less it does it.. BTW I haven't had a chance to put my carbon filters back in... But I can say I do notice a power increase.

Any idea how long this will take? Will disconnecting the battery and resetting anything help? The obvious solution is to put the filters back in, but I don't want them and if the car will eventually adjust I'll wait it out. I'm just worried I may be causing damage.

Holy **** I'm dumb.. I just realized what the issue is.. I forgot to tighten the metal clasps on the upper portion of the intake.. THAT is why it's sputtering, it's gotta be. I'm sorry guys.. I'm dumb lol....wow... Ha oops
